一种新型皮肤外牵拉装置的设计和研发

Design and Development of a New Type of Skin External Stretch Device

目的针对不规则巨大创面,设计一种可同时应用VSD负压装置的新型皮肤外牵拉装置。方法应用强韧缝线代替金属皮钩或克氏针进行牵拉创面,然后通过设计的皮肤牵拉装置逐渐缩短缝线以达到牵拉闭合创面的目的。结果成功设计出一种不受创面形状和大小限制的,并可同时应用VSD敷料装置的皮肤外牵拉装置,并获得国家专利。结论通过这种以逐渐缩短缝线为原理的皮肤牵拉器可达到牵拉皮肤闭合创面的目的,较其他皮肤牵拉装置更具优势。

Objective To design a new type of skin external stretch device which can be applied to VSD negative pressure simultaneously for irregular large wound surface.Methods We used strong suture to stretch the wound instead of metal peaches and kirschner-wire,then shortened the suture which could be connected to the new skin stretch device gradually to achieve the purpose of the closure of the wound.Results A new skin external stretch device was designed and obtained,which was not limited by the shape and size of the wound.The external skin pulling device of VSD dressing device could be applied simultaneously.In addition,the national patent was obtained.Conclusion The skin drawer based on the principle of gradually shortening the suture can achieve the purpose of pulling the skin closed wound surface,which is more advantageous than other skin traction devices.
